The Cosmic Interference Problem: Why Alien Signals Might Look Different

A new study from the SETI Institute suggests extraterrestrial signals may be harder to detect than previously thought. Plasma turbulence and stellar winds—especially around common M-dwarf stars—can blur narrow radio transmissions into faint, spread-out patterns.

By studying how plasma in our own Solar System distorts spacecraft signals, researchers propose new detection strategies designed to uncover these overlooked technosignatures.
